This project investigates the influence of authenticity on interest in the context of structured magnetic elastomers, considering the interaction between objective complexity and subjectively perceived cognitive load. Authenticity, defined as the degree of realistic representation of contexts, has been recognized as a crucial factor in promoting interest. However, the mechanisms through which authenticity affects interest, particularly considering the role of complexity and cognitive load, are still insufficiently explored. To address this research gap, an expanded theoretical framework is developed, integrating existing models of interest, cognitive load theory, and authenticity. This framework guides the design of empirical studies to investigate causal relationships between authenticity, complexity, interest, and cognitive learning outcomes. The focus is on using original visualizations and simplified model experiments, which are collectively provided in the groups of the Research Unit. The mixed-methods approach includes quantitative surveys using questionnaires and eye-tracking procedures, as well as qualitative interviews. Participants will be recruited from high school and engage in scientific activities involving magnetic elastomers at OVGU Magdeburg and TU Dresden. Eye-tracking data from a smaller sample will be collected to examine the cognitive processing and complexity of the learning materials. Statistical analyses of pupil size and saccades provide insights into cognitive load and information processing during learning. Data analysis will involve statistical modeling techniques such as structural equation modeling, hierarchical regression, and analysis of eye-tracking data. This allows for investigating the complex interactions between authenticity, complexity, interest, and cognitive processing, with eye-tracking data supporting the perception of complexity. Qualitative interview data will be thematically analyzed to provide a deeper understanding of underlying processes and mechanisms. The expected outcomes of this project include a refined understanding of how authenticity influences interest, considering complexity and subjectively perceived cognitive load. The results contribute to the development of evidence-based strategies for designing authentic learning environments that promote interest, optimize cognitive processing, and improve cognitive learning outcomes. They will further support the Research Unit’s general outreach activities. Additionally, the empirical findings provide a foundation for future research in the field of situated learning and instructional design, aiming to enhance the accessibility and relevance of research findings for all members of the Research Unit and promote interest in scientific activities.
